WINDMILL.

SPECIFICATION forming part of Letters Patent No. 402,353, dated April30, 1889.

' Application filed January 2, 1889 $erial No. 295,166. (lflo model.)

To all whom it may concern:

Be-it known that I, CONRAD SonMELzER, a citizen of the United States ofAmerica, residing at Pueblo, in the county of Pueblo and State ofColorado, have invented certain new and useful Improvements inWindmills; and

.I do hereby declare the following to be a full, clear, and exactdescription of the invention, suchas will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in thatclass of windmills which are commonly known as horizontal, the revolvingwheel, actuated by the force of the wind, being attached to a verticalshaft; and my invention consists, chiefly, in the construction andcombination of the parts and in the arrangement of the governingdevices, whereby. the area of the vanes presented to the wind isregulated by the force of the wind, as will be hereinafter fully setforth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of awindmill constructed in accordance with my improvement. Fig; 2 is avertical sectional view. Fig. 3 is a plan View. Fig. 4 is a horizontalsection.

The wind-wheel is supported by a suitable frame, consisting ofhorizontal beams A and A, which are provided centrally with bear ings.These beams A A are secured to the vertical beams 13-13, which areattached at their lower ends to suitable sill-pieces, to which they arebraced.

To the under side of the beam A is bolted a block or bearing, at, havinga central recess, within which the upper end of the casting 0 lies,which casting has at its under side a recess, c, in which the upper endof the shaft D bearsr This shaft passes through central openings in thecastings or bearings d d, and is stepped on asuitable block, d abovewhich the shaft D is provided with a beveled pinion, which meshes with apinion attached to the driving-shaft.

The vertical shaft D rotates freely, and is provided with hubs E and E,each of which is composed of corresponding upper and lower halves,between which are bolted a series of radial arms, E to which are securedvertical vanes or wings F. The inner edges of the vanes or wings abutagainst rings 6', which are secured to the arms to brace them. G refersto a semicircular covering or shield, which consists of a number ofvertical pieces, g, attached to a frame, H, made up of an upper andlower ring, h and h, which are rigidly connected to each other by fouror more vertical strips, '0' 2', having inwardly-bent ends, throughwhich bolts pass for securing the rings and strips to each other. Thesebolts also at tach the outer ends of the radial armst' and 2" above therings, the inner ends of said arms being secured to disks or hubs I andI.

Attached to the hub I, or formed integral therewith, is the casting O,hereinbefore mentioned, and to the lower hub, I, is attached a hollowbearing, through which passes the shaft D. This bearing d lies partiallyover the bearing 01, located above the beam A. One-half of the upper andlower rings, h and h, have attached thereto segmental pieces Z0 Z0, towhich the strips which form the semicircular shield are secured, andnear one edge of this shield is attached an outwardly-projecting armorplate, which carries vertical and horizontal pulleys Z and 1, over whicha cord passes. This plate may also be provided with a guide-perforationbeneath the pulley, which is mounted on a horizontal axis, to

prevent displacement of the cord. To the upper ring, h, on the oppositeside from the shield, and midway between the edges thereof, is rigidlysecured a small vane or blade, H, which is bolted to a projecting arm,and through a perforation in this vane a cord, m, passes, which cord isused for moving the main vane to occupy a position parallel with thesmaller vane.

L refers to the main vane, which is rigidly attached to a suitable bar,a, pivoted at its inner end to the upper hub or disk to one side of thesupplemental vane H, so that when the cord which passes through thesupplemental vane is drawn the main vane will be moved so as to beparallel with the smaller or supplemental vane. Above the upper ring issecured a segmental plate, 0, beneath which the arm of the main vanemoves, and above theplate travels an anti-friction roller car ried bysaid vane. The cord 19, which passes over the pulleys, is attached atone end to the main vane, the opposite end thereof being provided with asuitable weight.

In operation my improved windmill is automatic, and when there is aheavy wind or gale the small fan or vane, which is rigidly bolted to theframe carrying the shield, will be acted upon by the wind, so as to movethe same toward the main fan, thus moving the shield to protect thewheel from the wind, or only leaving a small portion of the wheelexposed to the wind. When it is desired that the wheel should not beacted upon by the wind, by drawing upon the cord connecting the main fanand smaller fan to each other they can be brought together, so as tothrow the shield in front of the wheel, and this cord can be secured tohold the vanes parallel to each other.

I am aware that prior to my invention windwheels have been provided witha movable shield adapted to be operated by vanes or fans, so that saidshield could be moved in front of the wheel to protect the same, and Ido not claim such broadly as my invention; but

What I claim as new, and desire to secure by Letters Patent, is-

1. In a wind wheel or engine, the combination of a vertical shaft havinghubs with radial arms to which are attached vertical blades, a movableframe made up of upper and lower rings rigidly connected and providedwith segmental pieces, to which are attached vertical strips forming asemicircular shield, a small fan or vane rigidly attached to the upperportion of the frame, and a fan or vane pivotally attached to one sideof the center of the movable frame and provided with a roller whichmoves upon a segmental plate, under which the arm of the main fan orvane passes, a weighted cord attached to the main fan and passing oversuitable guide-pulleys carried by the shield-supporting frame, and acord attached to the opposite side of the main fan and guided throughthe smaller fan for drawing said vanes parallel with each other, theparts being organized substantially as shown, and for the purpose setforth.

2. The combination, in a wind wheel or engine, of a movable frameprovided with a semicircular shield, a small vane or fan rigidlyattached thereto, and an outwardly-projecting arm carrying a pulley, amain vane pivoted to one side of the center of the shieldcarrying frameand provided with a weighted cord, whereby the shield is automaticallymoved by the force of the wind, and a vertical wheel journaled withinthe shield-carrying frame, substantially as shown, and for the purposeset forth.

3. The combination, in a wind-engine, of a central wheel, ashield-carrying frame made up of the upper and lower rings rigidlysecured to radial arms, vertical bars having inturned ends which arebolted to the rings and radial arms, a segmental plate beneath which thesupporting-arm of the main fan passes, said fan carrying a roller whichtravels above said plate, and segmental plates attached to the rings forsecuring thereto strips forming the shield, substantially as shown, andfor the purpose set forth.

4. The combination, with a horizontal wind wheel or engine, of a framecarrying a shield and a small vane or fan rigidly secured thereto, amain vane or fanmounted on a suitable horizontal arm pivoted to one sideof the center of the shield-carrying frame, and means, substantially asdescribed, for moving the larger vane so as to lie parallel with thesmaller vane, substantially as shown, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

CONRAD SCHMELZER.
